What is the probability of obtaining five heads in a row when slipping a fair coin?
kipiarov [429]
We want the coin to land on heads on 5 out of 5 flips.

Each time, the coin has a 1/2 chance of landing on heads.

Since we want it to land on heads 5 times in a row, we multiply 1/2 five times to get the probability.

(1/2) * (1/2) * (1/2) * (1/2) * (1/2) = 1 / (2*2*2*2*2)

= 1 / 32

There is a 1/32 chance of landing heads five times in a row.

Have an awesome day! :)

Find the volume of the sphere. Round your answer to the nearest tenth.
Viktor [21]

Answer:

Volume of sphere = 44.57 cm³

Step-by-step explanation:

Given:

Diameter of sphere = 4.4 centimeter

Value of π = 3.14

Find:

Volume of sphere

Computation:

Radius of sphere = Diameter of sphere / 2

Radius of sphere = 4.4 / 2

Radius of sphere = 2.2 centimeter

Volume of sphere = [4/3][π][r³]

Volume of sphere = [4/3][3.14][2.2³]

Volume of sphere = [4/3][3.14][10.648]

Volume of sphere = [1.333][3.14][10.648]

Volume of sphere = 44.568

Volume of sphere = 44.57 cm³

Use formula A=x^2\ in^2 connecting the area of the square and the side length of the square.

Since the area ofthe square is 55 square inches, we have

x^2 =55\\ \\x=\sqrt {55}\ in
